The invention discloses an antenna device which has a lens or a passive element acting as a lens. The antenna device includes: and a wave beam forming unit which forms electromagnetic wave beams with different orientations, and the wave beam forming unit including an antenna surface for transmitting and receiving the electromagnetic waves and a plurality of beam ports for inputting and outputting radio frequency electric signals; at least two transmission signal adjustment units; a transmission signal providing unit; at least two reception signal adjusting unit; a reception signal generation unit; and a wave beam control unit. In the wave beam forming unit, at least two wave beam ports for transmission are placed at one side of the wave beam forming unit and are spaced from each other at a predetermined interval. And at least two wave beam ports for reception are placed at one side of the wave beaming forming unit and are spaced from each other at another predetermined interval. The wave beam forming unit includes an antenna array and Rotman lens, or includes a dielectric lens and an array antenna.
